去年,我们再次进行了秋白菜地膜覆盖栽培试验,结果证明,覆膜秋白菜比露地栽培的每亩增产4,210公斤,增产率达54.6%,扣除地膜成本(40元)每亩纯增收200～250元.地膜覆盖栽培秋白菜方法简单,播种后田间不必铲趟,并可减少灌水次数.但是,栽培时必须注意:比一般栽培延迟播种3～5天; Last year, we conducted another test of film mulching cultivation of autumn cabbage. The results showed that the yield of mulberry leaf covered 4,210 kilograms per acre compared with that under field cultivation, and the yield increase rate reached 54.6%. After deducting the cost of mulching film (40 yuan) Yuan mulching mulching cabbage method is simple, the field after sowing do not have to shovel times, and reduce the number of irrigation, but must pay attention to the cultivation: delayed sowing than the average 3 to 5 days;
